To all whom it may concern:

Be it known that I, SA U L. MrLnUnN, citizen of the United States, residing at Kennett, in the county. of Dunklinand State of Missouri, have invented certain new and useful Improvements in Attachments for Seed-Planters, of which the following is a specification, reference being had to the ace companying drawings.

his inventionreiate's to an attachment forplantersand more particularly to a gage 1 shoe whereby the seed may be'e'vcnly planted at a predetermined depth.

The invention has for its principal object to provide a'devicefor the above purpose attachable to planters of the ordinary construction and which may be easily and quickly adjusted when it-is desired to vary the depth of the furrow in which the seed are deposited. Another and more specific object; of' the invention-resides inthe provision of a single plate or casting longitudinally curved for engagement upon the forward edge of the upwardly curved furrow-opening runner, said plate being provided w th a central longitudinalslot in one end to receive the runner whereby the plate is held against as will become apparent as the description transverse shiftingmovement, and means for adjustably' clamping the plate at its other end to the runner.

The invention has for a further object the provision of a planter attachment of the above character which is exceedingly simple in col'istruction, may be produced at small iminufacturing cost and is highly durable,

etlicient and reliable in practical use.

lVith the above and other objects inview proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a. full understanding of. the invention, reference is to be had to the following description and accompanying drawings, in

. which Figure 1 is a perspective view-of a seed depositing boot showing my improved attachment applied to the furrow-opening runner thereof; Fig. 2 is a horizontal section illustrating means for clamping the shoe to the runner; Fig. 3 is a sectiontaken on the line 33 of Fig. 1; Fig. 4 is a detail plan view of one end of theshoe.

Referring in detail to the draw1'ng,.5 des- Specificationof Letters Patent. Application filed June 16. 1913. Serial No. 773,972.

Patented Sept. 9,] 913.-

ignates a seed depositing boot which may be furrow-opening runner or sword which exten ds forwardly from the lower end of the bootand is upwardly curved as at 7,said runner from its forward end extending.

of the boot Y My improved shoe attachment embodies a single integral casting or plate 8 which is longitudinally curved as shown and is of uniform width throughout its entire length.

vided with-a centrallongitudinally extendmg slot 9, said slot opening upon the end of .verscly inclined as indicated at 10 to provide a flaring entrance'or mouth to said slot.

The shoe plate 8 adjacent its other or upper end is provided with spaced rectangular openings 11 to receive rectangulm'ly formed loosely-v disposed in said openings. U pon these bolts, the clamping plate 13 is loosely" mounted, said plate having openings in its opposite ends to receive the bolt. This plate is preferably curved slightly, as shown, and upon the threaded ends of the-bolts '12, the nuts 14. are engaged wherel'iy the plate with the furrow-opening runner 7.

It is a well known fact that in order to obtain the best results in the planting of cotton, the seed must not be planted either too deep or too shallow. It is therefore necessary, in view of the fact that the character of the ground varies indifferent places to adjust the furrow opener so that a furrow of the required depth will be formed in the movement of the machine. Heretofore, a let-his lever is constantly actuated by the operator to suit the nature of theground so that the seed will not be planted too deeply necessary, as the seed deposited from the rearwardly and upwardly to the upper end At one end of said pla te, the same is pro-.

the plate'and having its opposite'edges reshank portions of the bolts 12 which are' ver has been provided for this purpose and in softground or, too shallow in hard of any approved form, and 6 designates the 13 may be -forced .into clamping engagement boot 5 into the furrow will be planted at the same depth in the movement of the machine over the field. By providing the broad fiat plate extending upon opposite sides of the furrow opener, the same Is prevented from sinking into the ground when soft places are encountered. so that the planting of all of the seed at the same depth throughput is assured. The provision of the slot 9 in the lower end of the shoe late obviates all liability of transverse shi ing or turning movement of the shoe upon the runner.

From the foregoing, it. is believed that the construction of my invention and the manner in which the same is to be used will be clearly and fully'understood.

The device is extremely simple in itsconstruction and may be easily and quickly attached to all types of planters now in gen-v eral use without necessitating any alteration whatsoever in-their construction.

The invention may also be produced at very small manufacturing cost. and will serve the purpose for which the same is de vised in a highly efficient manner.

While I have above described the preferred form and construction of my invention, it will be understood that the same is susceptible of'many modifications without.

departing from the essential features or sacrificing any of the advantagesithereof except as defined in the appended claims.

Having thus described the invention, what is claimed is: 'j I 1. The combination with the furrow opener of a seed planter, of a gage shoe consisting of a longitudinally curved plate of uniform width throughout its length adapted for engagement upon said furrow opener and extending upon opposite sides thereof, and means for clamping said shoe to the furrow opener r 2. The combination with the furrow opener of a seed planter, of a gage shoe comprising a longitudinally curved plate adapted for arrangement upon the-forward lower edge of said furrow opener and to extend upon opposite sides thereof, said plate being provided with a longitudinal slot in one end to receive the furrow opener, and

means for-adjust'ably clamping the plate at' its other end to the furrow opener.

3.'The combination with the .furrowopener of a seed planter, of a gage shoe consisting of a longitudinally curved plate of uniform width throughout its length, said plate being adapted foriarrangement upon the forward lower edge of the furrow opener and to extend upon each side thereof and provided with a central longitudinal slot in one of its ends, the open end of said slot being flared and adapted to receive the furrow opener, a pair of bolts loosely n punted in the opposite end of said plate and extending upon each side of the furrow opener, a clamping plate loosely engaged upon said bolts, and nuts threaded upon the bolts to clamp said plate against the furrow opener. In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
